Introducing the wake_up_info() patch in kernel enables intelligent wake ups for devices. The new wake up function improves the performance of the device and helps conserve battery life.
The purpose of the wake_up_info() patch is to provide callers with the ability to pass information to the callback function registered inside the wait structure. This is a big improvement from the previous version, which did not allow passed information about the cause of the wake up.
The current version of the Linux kernel (2.6.0) is inefficient when it comes to wake up calls. As a result, freshly woken up tasks are forced to go through additional steps to get access to useful information. This not only wastes time but also creates inefficiencies within the system.
Overall, the wake_up_info() patch is a useful update for users looking to increase the efficiency of their Linux operating system. Whether you're a developer or just a user, this patch is definitely worth considering, and I highly recommend it.
